Lets say I have two string: "$7.99" and "$16.99"

Now, I'm trying to add these values together to get "$24.98". The money could be in a different currency than USD, but the two strings will always be the same currency.

I'm trying to use a combination of the monetize gem (https://github.com/RubyMoney/monetize) and the currency gem (https://github.com/hexorx/currencies)

The currency gem contains all the currency information.

Here is my code:

require 'monetize'        
require 'currencies'
Money.default_bank = ISO4217::Currency::ExchangeBank.new # from the currencies gem doc
m1 = Monetize.parse "$7.99"
m2 = Monetize.parse "$16.99"
m = m1 + m2
puts m

I get the error

I18n::InvalidLocale: :en is not a valid locale

Even though I loaded the currency bank

`I18n.config.available_locales = :en` – Andrey Deineko Nov 04 '16 at 23:32
can I set every locale available in the Currency::ExchangeBank to be available? I have a lot of potential currencies/locales and would not want to explicitly set each one – Im_Matt_Murdock Nov 04 '16 at 23:45
[here is the list](https://github.com/svenfuchs/rails-i18n#available-locales) of all locales, you can allow all of them if you want – Andrey Deineko Nov 04 '16 at 23:50
